SPECIFICATION' forming part of Letters Patent No. 678,656, dated July 16, 1901. Application filed April 22, 1901. Serial No. 56,868. (No model.)

To @ZZ whom, it may concern.-

Beit known that I, PETER G. GIROUD, a citizen of the United States, and a resident of Binghamton, in the county of Broome and State of New York, have invented a new and useful Time-Stamp, of which the followingis a specification.

My invention relates to a time-stamp, with the object in view of simplifying the structure and improving the action of the moving parts. v

A practical embodiment of my invention is represented in 'the accompanying drawings, in which- Figure 1 is a top plan view showing an arrangement of the several series of time-indicating symbols inwhich the minute-indicating series of symbols is located intermediate of the hour and meridian series. Fig. 2 is a view in side elevation, showing an larr-angement of the series of time-indicating symbols in which the hour and meridian series are located upon a single rim with the minute-indicating symbols at one side. Fig.` 3 is a view in end elevation, the timemovement being removed, showing the position of the drivinggear on the time-train in its position relative to the driven gear on the stamp-train, the position of the day-shifting lever being shown in full lines in the position which it occupies from the beginning until near the end of the day and in dotted lines the position which it assumes just before it is tripped to change the number of the day. Fig. 4 is a transverse section in the plane of the line 4 4 of Fig. 1. Fig. 5 is a transverse vertical section on the line 5 5 of Fig. l. Fig. 6 is a view in detail of the month-wheel and the cam on the day- Wheel back of it, showing the position of the operating-pawl at the limit of its backward movement and the position of the locking-dog just before it is released from the wheel. Fig.

7 is a similar view of the month-wheel, show-` ing the position of the actuating-dog when midway of its forward movement just as it has released the locking-dog and isabout to push the wheel forward one step. Fig. 8 is a sectional view in detail, showing the shaft on which the hour-wheel and the meridian-wheel are fixed, with thel minute wheel loosely mounted between them, as in Fig. l, and the gear for operating the day-wheel; and Figs. 9 and 10 represent vertical sections from front to rear through the stamp-train, the former lshowing the manner of mounting the series of time-'indicating symbols when the hour and meridian are on the rim of a single Wheel and in juxtaposition and the latter showing the manner of mounting the saidv symbols when the hour and meridian series are on separate rims and in juxtaposition.

In the accompanying drawings the casing of the stamp is not shown, and the plunger for pressing the record-receiving strip and ribbon into contact with the printing-Wheels is also omitted, it being understood that it may be of any well-known or approved form, my present invention relating particularly to the means for mounting and actuating the several series of time-indicating symbols and the arrangement of the stamp-train with respect to the time-train.

For the purpose of economizing space within the casing and for the further purpose of bringing the time-train and stamp-train into such relation that they may be supported in a manner to lend irmness and rigidity to the structure I locate the time-train, denoted as a whole by A, and which may be of any wellknown or approved form, with its central arbor cy above the actuating-shaft B of the stamptrain and connect the two by means of a gearwheel a on the rear end of the'central arbor a of the time-train and a gear-wheel h on the front end of the drive-shaft B of the stamptrain. This brings the foot of the time-trainsupporting frame on a level with the foot of the stamp-train-supporting frame and the top of the time-train frame somewhat below the top of the printing-wheels of the stamp-train and admits of firmly securing the parts together by upper and lower posts or girders C C in a firm and compact manner.

The several series of time-indicating symbols are preferably formed on the rims of wheels which may be conveniently termed printing-wheels. In the present instance six series of time-.indicating symbols are shown, each seriesformed on the rim of a separate wheel, with the exception of the ar- 'of the remaining sets.

rangement shown in Figs. 2 and 9, where the hour and meridian series are formed on the rim of a single wheel.

Referring to the arrangement shown in Fig. l, the year-wheel is denoted by D, the meridian-wheel by D', the minute-wheel by D2, the hour-wheel by D3, the day-wheel by D, and the month-wheel by D5. Of these printing-wheels the meridian-wheel and the hour-wheel (denoted, respectively, by Dand D3) are fixed to rotate with the shaft or spindle d, while the minute-wheel D2 is mounted loosely on a hub or sleeve d', iiXed on the shaft cl intermediate of the wheels D D3, and the year, day, and month wheels are loosely mounted on the shaftcl. The meridian-wheel is removably fastened to the shaft d by means of screws d2, which extend through its hub into the hub or sleeve d/ on the shaft d, as clearly shown in Fig. 8, while the hour-wheel D3 is fastened to the shaft CZ with its hub abutting against the end of the sleeve Cl, leaving space between it and the meridianwheel for the minute-wheel to rotate freely on the hub or sleeve d@ The shaft d also has fixed on its front end a gearwheel E, which is in position to intermesh with a crank-wheel E', mounted on the supportingframe immediately below it, the said crankwheel being provided with a crank-pin c for engaging a lever-arm F, fixed to a shaft f at or near the foot of the stamp-train-supporting frame, which shaftfhas fixed thereon the support for the pawl which actuates the day-wheel. It thus follows that the rotary movement of the shaft' CZ actuates the meridian-wheel, the hour-wheel, and the daywheel, the month-wheel being actuated by a cam on the day-wheel, as will be hereinafter more particularly explained, the year-Wheel by hand, and the minute-wheel by a spurwheel b, fixed on the drive-shaft B of the stamp-train and intermeshing with a gearwheel b2, `ilxed on the side of the minute-wheel. The shaft d, which operates the three wheels D D3 D, is given a step-by-step movement at intervals 0f one hour by means of a cam b3, (see Fig. 5,) fixed on the drive-shaft B, driven directly from the arbor d of the time-train.

The several sets of actuating-pawls and their companion locking-levers are quite similar in structure and operation, although their respective sizes and lengths of stroke may be more or less modified to suit their particular locations and the parts which actuate them. A specific description of one set will sufce to clearly disclose the structure and operation The set chosen for specific explanation is that which operates the month-wheel D5 and is under the control of a snail-cam G, fixed to rotate with the daywheel D4. The pawl-support for this set is denoted by H (see Figs. t5 and 7 and consists of an arm uprising from a hub loosely mounted on the shaft f and provided with a heel 7L, to which an actuating-spring 7L is attached, the opposite end of the spring being attached to the supporting-frame. In the upper end of the support H the pawl h2 is pivoted to swing freely in one direction, but is prevented `from swinging in the opposite direction by means of a stop h3 on its support. The pawl h2 is provided with a laterally-projecting pin h4 on its side, which when the pawl is in its advanced position (shown in Fig. 5) rests under the foot of the short arm 1l of a lockinglever pivotally mounted on a piu l, the long arm 11' of said do? bein(r rovided with a nose i i2, adapted to fit between two successive teeth g on the face of the month-wheel D5. The teeth g on the face of the month-wheel preferably consist of pins having' their outer faces flattened. The locking-dog is held normally with its nose 2 in locking position between two successive teeth g by means of an actuating-spring i3, one end of whichis secured to a heel t" on the locking-dog and the opposite end to a pin or suitable fastening on the supporting-frame. An operating-arm h5 is fixed to and projects upwardly from the hub of the pawl-support into posit-ion to be engaged by the periphery of the snail-cam G. As the snail-earn rotates, together with the wheel D4, to which it is attached, it gradually forces the arm h5 backward and with it the pawl-support H, the pawl h2 rocking forwardly to permit the pin l1,4 to pass under the foot of the lock-lever until the parts reach the position shown in Fig. G, where the arm h5 is about to drop from the outermost point of the cam C to theinnermost point. 1n this position the pawl 7a2 has been thrown back into extended position byits actuating-spring 71. on the back ofthe support H, and the spring 7L is distended, tending to rock the support ll forward as soon as the arm hi is released from the cam. As soon as this release takes place the first effect of the pawl 7b2 is to rock the lockinglever out of engagement with the teeth on the month-wheel, as shown in Fig. 7, by the engagement of the pin 7b4 with the back of the short arm t' of the locking-lever, and the further movement of the support ll and the pawl carried thereby in a forward direction under the tension of its actuating-spring h will be to rotate the month-wheel one step by the engagement of the pawl h2 with one of the teeth g of the wheel. Before the pawl h2 has advanced the wheel a complete step the pin h4 will have passed under the foot of the locking-lever into the position shown in Fig. 5, permitting the latter to rock back with its nose 2 resting on one ofthe teeth g of the said month-wl1eelD5,and the moment the pawl h2 has completed its forward movement or has rocked the wheel D5 the distance between two consecutive teeth the nose t2 ot' the lock-lever will drop into position between two consecutive teeth of the wheel D5 and stop the further rotation of said wheel. In the same manner the day-wheel D4 will be operated by the rocking of its pawl-support H through the rocking movement of the lever F under the control of the crank-pin c on the crank-wheel E',

in gear with the wheel E on the shaft d. The position where the lever F is about to be tripped by the passing of the crank-pin. is shown in dotted lines in Fig. 3. In the same manner also the meridian and hour wheel or wheels, and hence-the shaft d and parts carried thereby,are operated by the pawl on the support II2 under the control of the snail-cam b3 on the shaft B. The position of the parts shown in Fig. 5 is that which they assume just after the snail-cam b3 has permitted the pawl and its support H2 to rock forward to the limit of its forward movement on the meridian or honr wheel D or D3. The operation as a whole may be briefl stated as follows: The time-train through its centralarbor a and the gear a' b rotates the shaft B and the spur-wheel b', which in turn rotates the minute-wheel D2, causing it to present at its top or wherever the printing is to take place that type which denotes the particular minute corresponding to the minute of time. When the sixty minutes have been successively presented, the cam las on the shaft B will have reached the point where the pawl h2 will escape from its outermost point and fall toward the center of the cam,

thereby, in the manner hereinbefore particularly described, rotatingr the meridian and hour wheels D/ and D3 one step. As the meridian-wheel is provided with A. M. type at each step for twelve consecutive hours and then with 13. M. type for twelve consecutive hours, it will denote the proper position of the hour, whether forenoon or afternoon. As the hour-wheel D3 is fixed to turn together with the meridian wheel and the shaft d, the typel denoting the successive hour will be brought into printing position and the shaft d, through the gear E, will have advanced the crank-wheelE one of its twentyfonr steps toward the completion of a day. When the twenty-fourth hour or the-termination of the twelfth hour P. M. has arrived, the crank-pin e will have been brought into position to escape from the lever F and under the tension of its actuating-spring and the support H will be rocked forward, forcing the day-wheel D4 one step to bring the type denoting the succeeding day into printing position. When thirty-one consecutive days have been thus presented, the cam G, carried by the day-wheel, will have reached a position where the arm h5 Will have been allowed to escape from it and the month-wheel under the control of the pawl h2 will be advanced to bring the type denoting the succeeding monthinto printing position. Whenever the month has twenty-eight or thirty daysinstead of thirty-one, the operator may advance the day-wheel three steps or one step to complete the thirty-one by operating the lever F by hand. W hen the year has been com pleted, the operator may move the year-wheel D one step by hand, the latter being conveniently held in its adjusted position bya friction-brake of any well-known or approved form.

Among the advantages which my present structure and arrangement presents particular attention is called to the simple movement of the pawl. h2 and its companion, by which it passes the locking-lever without any tendency to disturb it and with very slight drag and the simple manner in which it on its return movement rocks the locking-lever out of engagement with the wheel and then at the proper moment releases it so that it may surely drop into locking position and hold the wheel against lost motion. The arrangement of the wheels on the shaft d and the manner in which it serves by its rotary movement to transmit power to the several wheels` while forming a support for vthose wheels that move loosely thereon is also a matter of econornyin construction and serves to simplify `and Arender more durable the structure as a whole.

Where the series of time-indicating symbols denoting the hour and meridian arek placed upon a single rim, as represented by D6 in I1`igs.e2 land 9, bringing the hour and meridian into juxtaposition, the minute series is placed after these two series, making the reading Month, Day, Meridian,7 and Minute The same reading may also be Obtained when the hour and meridian vseries are on separate wheels, as in Fig. l0, and placed in juxtaposition.

Itis obvious that changes might be resorted to in the form and arrangement of the several parts without departing from the spirit and scope of my invention. Hence I do not wish to limit myself strictly to the structure herein set forth; but
